MultiCryptos confirmed
SCAM.
Been waiting over a week for this payment:

I just realize now the existence of this not paid investment. What happended is that coinpayments deslisted MINTCOIN for few days or hours (at the right moment that our script should had process your payment), thats why your investment has not been paid.
I am going to pay it now, expect it in next minutes. But next time contact us at
contact@multicryptos.com or pm me if there is this kind of problem and we will solve it.
We did all payments until now, any other user has complained.
Thanks and apologies.
